We will be in Istanbul in May and have four days to see a bit of the Aegean. Which is a good town to make our base? We have been recommended Selcuk and Izmir. What is the best way to travel to and around this area, given our short time frame?
http://www.turkeytravelplanner.com is a very good resource for Turkey information. I can say that I stayed in Selcuk for 24 hours, and liked the town a lot. My Lonely Planet characterized it as just a way-station and "nice enough", and it was much nicer than their description. Whether it would suit your goal of seeing the Aegean, I don't know (I was there to see Ephesus, and it's also a convenient springboard for other ruins).
